Here's how fans of The Greatest Spectacle in Racing and the sport as a whole reacted, starting with driver Graham Rahal:

Amazing news for @indycar. Why? Because one network, more races on the main @nbc channel, and continued growth and development with a partner committed to working together! #Indycar is on the rise, and this is a HUGE step. Fans, you now have one spot to find us, be excited! https://t.co/hDNBwyMIXm

Burke Magnus, #ESPN Exec VP of Programming:"We have had a wonderful & rewarding relationship with @IMS the #Indy500 & #INDYCAR & it has been our honor to be partners for so many years. We look forward to the rest of our events this season & wish them all the best in the future"

This comes as no surprise. @NBCSports has done a tremendous job covering @IndyCar in recent years, although there are quite a few members of the ABC/ESPN crew that I really respect and hope land on the new NBCSN one. https://t.co/fm7JIevdSu

ABC's IndyCar coverage has been terrible for some time now but this is undeniably the end of an era. It may not bump the ratings a ton but at least NBC/NBCSN respects the series. https://t.co/XAxBUXEUFH
